Thoughtful Design: The aviator hat is designed to be windproof and warm. It features removable vintage helmet goggles with a hard surface and chemical resistance. Stronger elasticity reduces deformation or breakage. Superior Fabric: The outer layer is made of cotton and faux fur for wind protection. Hat circumference is approximately 22-23.6 inches. It fits snugly against the skin, radiating warmth to the head and completely covering the ears to keep warm. Unique Styles: This vintage aviator hat for men and women borrows its style from the traditional trooper hat, but with a modern twist. Designed in uniform colors with fur detail, it offers a sharp look while keeping you warm. From snow-covered forests to city streets, this aviator hat serves the best of both worlds. One Size Fits Most: Our winter trapper hat is designed to comfortably fit most head sizes and shapes and is suitable for all hair types. A chin strap secures the hat for improved warmth and fit. Washing Instruction: Machine wash with a laundry bag, hand wash, do not bleach.
